Claims

[Claims for Utility Model Registration] (1) A first device whose terminal on the fixed electrode side is pre-molded with resin.
A conductive elastic member in contact with the fixed electrode side terminal is inserted into a space formed inside a molded body formed by fixing a molded body and a second molded body in which a bimetal side terminal is molded in resin in advance. A structure for an overcurrent detection device, comprising a positive temperature coefficient thermistor piece pressed into contact with the bimetal side terminal, a bimetal piece provided on the bimetal side terminal, and a fixed terminal provided on the fixed electrode side terminal. (2) the void is a hole with at least one side open;
The structure of the overcurrent detection device according to claim 1, which is a registered utility model and is configured such that the conductive elastic member and the positive temperature coefficient thermistor piece can be inserted after the molded body is created. (3) Structure of the overcurrent detection device according to claim (1) or (2) of the utility model registration claim, wherein one side of the terminal on the fixed electrode side extends long to form the fixed terminal. body. (4) The case further includes a case for storing the structure, and the case is provided with a stepped portion for abutting the mold body when inserting the structure into the case. A structure of an overcurrent detection device according to any one of items ) to (3).
